Hi there. I run Exchange 2003 behind the Astaro software firewall. I outward deliver mail directly (i.e. do not use the smtp proxy) via two SMTP connectors in exchange.
One delivers mail via a smart host (ww.authsmtp.com) to avoid our outgoing mail being regarded as 'suspicious' by receiving servers. The other connector we use to deliver mail directly via DNS, as this one handles 'forwarded' mail; i.e. we send a copy of incoming mail to Blackberries, google mail etc. and obviously our smart host could not accept these emails as they are from thousands of different people (so we have to send them direct).
I tried the smtp proxy the other day. Using transparent mode. Not using the smart host.
1. incoming email is fine
2. outgoing email that goes via the DNS (direct) connector is fine
3. But outgoing email that was supposed to go via the smart host connector authsmtp.com can not be delivered by Exchange 2003 and remains in the queue.
What's the problem and what's the solution here? Do I have to tell my Exchange connector to deliver to the firewall (and not to authsmtp.com) and then confgure Astaro's smart host function for onward relay. If so, how will email I need to send NOT via authsmtp get handled by Astaro? (i.e can what have two ways of delivering outgoing email by Astaro?).
Hope there is a solution please!
Thanks ...
